Incredible quality and you basically have two bags for protection. In addition, I was able to fill it up with 55lb (25KG) of sand. This is definitely not recommended but the quality of the sandbag is great and will most likely endure it (fingers crossed :D )
Very good Quality, I used the plastic bag in came with to have an extra layer to fill in my bag, but is realy not needed. Its double stitched, it has suport at the grips so it doesnt squesse your fingers together when you lift, what is very good. The Material of Bag is very sturdy. The inside bag closes with two velcro strips, so send can never run out. I fill in 15 Kg very easy, i think 16-17 kg is no problem... if you need that. They sent wrong product first but noticed it before it arrived and sent me the actualy order with DHL very quickly... what makes them very good sellers. So no worries, this product is the Top quality, and Seller even more. Allot of thumbs up!!
